Description

Technical Field

[0002] In the field of chemical mixing and processing, the traditional process mainly uses chemical pumps to transport chemical compounds and mixtures to the mixing equipment, and implements a one-time feeding processing mode based on the equipment volume. The operating speed of conventional mixing equipment is generally in the range of 30-200 rpm. It is worth noting that when the speed exceeds the conventional range, the internal fluid resistance generated by the stirring liquid shows a nonlinear growth, which directly leads to an exponential increase in the equipment torque.

DETAILED DESCRIPTION

[0014] In order to make the purpose, principle and structure of the present invention more clear, it is further described below in conjunction with the drawings and specific embodiments.

[0015] Embodiment 1: This embodiment provides a supergravity mixing processing equipment.

[0016] See also Figure 1 , 2 3. The structure of the processing equipment includes a closed housing 1, the interior of which is divided into an upper cavity and a lower cavity by a horizontal partition. An electric motor 2 and a coupling 3 are installed in the upper cavity, and the electric motor 2 is connected to a main shaft 7 vertically arranged in the lower cavity through the coupling 3 to achieve power transmission.

[0017] The lower cavity is provided with a fixedly installed outer cylinder 4, the side wall of the outer cylinder 4 is provided with a liquid inlet 12 which is 90° perpendicular to the outer cylinder 4, the top of the outer cylinder 4 is provided with a volute 5, the top of the outer cylinder 4 is sealed with the volute 5, and the lower part of the outer cylinder 4 is provided with an air inlet for air intake.

[0018] The inner wall of the outer cylinder 4 is provided with multiple layers of annular isolation plates 11 at intervals along the axial direction. The annular isolation plates 11 are used to receive the liquid thrown onto the inner wall of the outer cylinder 4 and increase the contact area between the liquid and the gas in the device, so that the liquid is mixed with the gas again. The inner wall of the outer cylinder 4 is provided with multiple liquid reflux grooves at equal angles corresponding to the areas of each isolation plate 11, so as to guide the liquid to quickly flow back to the bottom of the outer cylinder 4. A liquid outlet 13 is provided at the bottom of the outer cylinder 4.

[0019] The outer cylinder 4 adopts a barrel structure, which ensures the stability of the equipment and is conducive to the uniform distribution and efficient mixing of materials in the equipment. The reflux groove can preferably be set to a size of 10mmx5mm and divided into four equal parts in the outer cylinder 4.

[0020] The main shaft 7 vertically penetrates the volute 5 and the outer cylinder 4, and the upper and lower ends thereof are fixed to the top of the volute 5 and the bottom of the outer cylinder 4 through the bearing seats 6 respectively. A main shaft cylinder 8 is coaxially sleeved on the outside of the main shaft 7, and a plurality of layers of inclined blades 10 are circumferentially arranged at the lower part of the main shaft cylinder 8. Each layer of blades 10 is spirally distributed around the axis of the main shaft 7 at an inclination angle of 55°. The bottom end of each blade 10 is the earliest part to contact the liquid, which is called the shear starting point 17, and the top end of each blade 10 is the last part to separate from the liquid, which is called the shear end point 18. The shear end point 17 and the shear starting point 18 of the upper and lower adjacent layers of blades 10 form a phase difference along the axial direction to form a continuous inclined shear channel. The electric motor 2 drives the main shaft 7 to rotate through the coupling 3, and the main shaft cylinder 8 on the main shaft 7 rotates accordingly, generating centrifugal gravity during rotation. Liquid and gas are lifted along the inclined shear channel under the action of centrifugal gravity, and at the same time, the liquid and gas can collide with the upper and lower layers of blades 10 in the inclined shear channel. The liquid is atomized into droplets as it impacts and detaches from the main shaft cylinder 8 and is thrown onto the inner wall of the outer cylinder 4.

[0021] The bearing seats 6 are respectively arranged at the top of the volute 5 and the bottom of the outer cylinder 4, and both are bearing seats 6 with waterproof and sealing structures.

[0022] A plurality of gas-liquid separation plates 9 are uniformly welded on the upper circumference of the main shaft cylinder 8. The gas-liquid separation plates 9 have an airfoil-shaped cross-section and are used to disperse the atomized liquid laterally onto the inner wall of the outer cylinder 4, thereby ending the tilting and lifting trend of the liquid and achieving preliminary gas-liquid separation.

[0023] The volute 5 includes a central inner circular flow channel 21 and a spiral outer circular flow channel 22 surrounding the outer side thereof. An opening is provided at the bottom of the inner circular flow channel 21. An assembly gap is provided between the opening and the top of the main shaft cylinder 8. A reflux gap channel 19 is provided around the bottom of the inner circular flow channel 21. One end of the outer circular flow channel 22 is connected to the inner circular flow channel 21, and the other end is connected to the air outlet 23. The air outlet 23 can be connected to the vacuum pump pipeline to form a negative pressure environment of -0.08 to -0.095MPa in the equipment through the vacuum pump. The through hole formed by the clearance between the volute 5 and the main shaft cylinder 8 realizes the gas-liquid circulation between the upper and lower cavities. The liquid reflux groove of the outer cylinder 4 and the reflux gap channel 19 of the volute 5 work together to ensure that the condensed droplets are efficiently guided back to the mixing area.

[0024] Preferably, in the present invention, the spindle barrel 8 can achieve stable and efficient operation at a speed of up to 1450 rpm / h. Through the continuous feeding and automatic discharging circulation mode, it is ensured that the solution inside the equipment will not remain for a long time during the mixing and processing of the solution. At the same time, the fluid resistance of the equipment during operation is extremely small, and it is only 0.0003768N after testing, which enables the equipment to achieve a large liquid processing volume while effectively reducing energy consumption and significantly improving production efficiency. Preferably, a temperature controller, a vacuum pressure controller, an air pressure controller, a variable frequency speed regulator, a PRC control cabinet and other equipment are installed outside the outer cylinder 4 in the shell 1 to achieve accurate monitoring and regulation of the equipment operating parameters.

[0025] The equipment adopts a continuous feeding and automatic discharging circulation mode. The fluid resistance is extremely small during operation, and there is less solution residue between the main shaft cylinder 8 and the outer cylinder 4. This not only ensures the high stability of the processing quality, but also achieves low energy consumption while ensuring the liquid processing quality. Under the high-speed rotation of 1450 rpm, the stable balance asymmetry of the equipment is less than 0.15g, thus ensuring the stability and reliability of the equipment under high-speed operation.

[0026] By increasing the diameter of the main shaft cylinder 8, the circumferential rotation of the main shaft cylinder 8 is enhanced, effectively increasing the linear speed of the rotating part. The solution outside the equipment is continuously sprayed into the supergravity mixing equipment by a metering pump, and the mixed solution flows into the finished product storage tank through the outlet of the equipment's external cylinder. This efficient operation method significantly improves processing efficiency.

[0027] The rotor of the main shaft cylinder 8 is equipped with symmetrically arranged blades 10. After a large number of tests, it has been verified that when the angle of the blades 10 is 55°, the efficiency of the mixed solution is ≥90%. The gas-liquid separation plate 9 on the upper part of the main shaft cylinder 8 ensures that the solution is evenly separated and finally discharged. At the same time, the equipment can operate under the operating environment of normal pressure (0.1013MPa), which reduces the pressure requirement for the operation of the equipment and improves the applicability of the equipment.

[0028] The gap between the outer cylinder 4 and the main shaft cylinder 8 forms a duct, and the porosity of the duct is precisely controlled at 0.5%. The inner wall of the outer cylinder 4 is circumferentially installed with an annular isolation plate 11, which can effectively receive the atomized particles of the solution thrown out by the centrifugal force of the main shaft 7, meeting the chemical processing requirements of the porosity solution capacity of 10m³ / h, ensuring the accuracy and efficiency of the processing process.

[0029] After the spindle 7 throws out the liquid by centrifugal force, the blade 10 repeatedly throws the liquid from top to bottom into atomized droplets. The reflux grooves evenly installed on the outer cylinder 4 ensure that the liquid can flow back to the finished product storage tank outside the equipment under the action of gravity acceleration, which greatly improves the material recovery rate and processing efficiency.

[0030] After the solution enters the duct of the equipment, it moves in a circumferential direction under the action of the high-speed rotation force of the rotor main shaft 7. The raw material is adsorbed by the gravity of the rotating blade 10, and the solution reciprocates upward and downward in the rotating blade. The gap between the rotating blades lifts the droplets upward. The high-speed centrifugal force, supergravity and the force generated by the supersymmetric dimension act together on the solution to make it more fully mixed. The solution metering pump at the liquid inlet 12 is installed horizontally at an injection angle of 90°, which ensures uniform injection and efficient mixing of the solution.

[0031] This equipment can operate stably in a wide temperature range of 25℃ - 400℃. It can also provide process solutions for various organic and inorganic substances such as dispersion, aggregation, combination, homogenization, oxidation and emulsification (liquid-to-solid ratio; ≥100 / 30), meeting the needs of different chemical production processes and having broad application prospects.

[0032] Embodiment 2: This embodiment provides a supergravity mixing processing system using the above-mentioned processing and mixing equipment.

[0033] See also Figure 4 The processing system comprises a first supergravity device and a second supergravity device connected in series, wherein the liquid inlet of the first supergravity device is connected to the material to be processed and the mixed liquid through a pipeline. The outlet of the air pump is directly connected to the air inlet of the first supergravity device through an air duct, and the air outlet of the first supergravity device is connected to the air inlet of the second supergravity device through a series pipeline to form a continuous gas processing channel. The liquid outlet of the first supergravity device is connected to the inlet of the transition box, and the outlet of the transition box is connected to the liquid inlet of the second supergravity device through a pipeline via a delivery pump to realize staged liquid delivery. The liquid outlet of the second supergravity device is connected to the solution tank, and the bottom outlet of the solution tank is connected to the liquid circulation loop. The main pipeline is connected to the liquid inlet of the first supergravity device, and a branch pipeline is set in the middle section of the main pipeline. The branch pipeline is equipped with a mixing nozzle for injecting the material to be processed into the circulating liquid and replenishing the mixed liquid to form a closed circulation processing system. The various devices in the system are connected by flanges.

[0034] Preferably, the material to be treated is concentrated chloride ions, the mixed liquid is desulfurization wastewater, and by-products fly ash and desulfurization gypsum can also be produced in the solution tank, and a circulation loop with chloride ion solution can be realized in the liquid circulation loop.

[0035] Embodiment 3: This embodiment provides an embodiment of treating desulfurization wastewater from a coal-fired power plant by using the technical solutions described in Embodiments 1 and 2.

[0036] A large coal-fired power plant has long faced the problem of treating high-concentration chloride ions in desulfurization wastewater. The chloride ion content in desulfurization wastewater is as high as 150,000 mg / m³, and traditional treatment methods are costly and ineffective. After using the technical solutions of embodiments one and two, air is sent into the equipment through a fan for oxidation processing, so that the chloride ion-containing waste liquid is separated into two layers by air oxidation. After equipment treatment, the chloride ion concentration in the upper layer is reduced by more than 50%. Taking the operating data on May 23, 2024 as an example, the original chloride ion concentration was 150,000 mg / m³, which was reduced to 68,653 mg / m³ after treatment, with an efficiency of 54%, and the equipment processing time is only 2 minutes. This achievement not only solves the environmental protection problem of the power plant, but also reduces the cost of wastewater treatment, improves the quality of by-product fly ash and desulfurization gypsum, and makes its chloride ion content meet the standard requirements.

[0037] Among them, the electric motor of this embodiment is 1450 rpm / h, the frequency conversion speed is 900 rpm / h, the metering pump is 3t / h, and the fan at the air inlet is 150m 3 / h.

The concentrated chloride ions are oxidized using supergravity mixing processing equipment and processing systems using air oxidation technology. The equipment processing time is 2 minutes and the reduction efficiency is 54%. No. 2 in the table above is a method of directly pumping the desulfurization wastewater containing chloride ions from the power plant into the super gravity mixing processing equipment and processing system. The air oxidation technology is used to reduce the chloride ion concentration of the desulfurization wastewater without concentrating the liquid. The equipment can achieve a 56% reduction efficiency in 1 minute. No. 3 in the above table is a method of reducing the chloride ion concentration by directly pumping the desulfurization chloride ion wastewater from the power plant into the ultra-gravity mixing processing equipment and processing system, using air oxidation technology. The equipment can achieve a 49% reduction efficiency after running for 1 minute.

[0039] Embodiment 4: This embodiment provides a method for producing fine chemical products using the above-mentioned ultra-gravity mixing processing equipment and processing system.

[0040] In the process of producing high-performance catalysts for a fine chemical company, extremely high requirements are placed on the uniformity of raw material mixing and reaction efficiency. Traditional mixing equipment is difficult to meet production needs, resulting in unstable product quality. After adopting ultra-gravity mixing processing equipment, by utilizing its high-speed rotation and unique internal structure, efficient mixing of raw materials within 3 seconds is achieved. Production efficiency has increased by 3 times, the active ingredients of the product are more evenly distributed, and product quality has been greatly improved. The company's product qualification rate has increased from the original 80% to more than 95%, and its market competitiveness has been significantly enhanced. Embodiment 5: This embodiment provides a method for synthesizing drugs in the pharmaceutical industry using the above-mentioned ultra-gravity mixing processing equipment and processing system.

[0041] A pharmaceutical company needs to accurately mix a variety of chemical raw materials during the drug synthesis process. In the past, the use of traditional mixing equipment not only took a long time to mix, but also easily resulted in uneven mixing, which affected the purity and efficacy of the drug. After the introduction of ultra-gravity mixing processing equipment, the rapid and uniform mixing of raw materials was achieved by precisely controlling the injection angle of the solution and the operating parameters of the equipment. The drug synthesis time was shortened by half, and the product purity was increased by more than 10%, which effectively reduced production costs and improved the economic benefits of the company.
